Evencure AA is a low viscosity aliphatic alcohol blend in an aqueous solution.
Evencure AC is an acrylic modified emulsion used as a curing membrane on freshly poured concrete.
Evencure BCP is a blend of bitumen and hydrocarbon resins emulsified in water.
Fine Particle, High Solids, Modified Bitumen Emulsion
Evencure W30 is a wax-based, sprayable curing compound formulated to cure freshly laid concrete. It is a low to medium viscosity, white pigmented emulsion of specially blended waxes.
Evencure XDS-NXGEN is a hydrocarbon resin blend cure blended with hardeners and densifiers to create the highest performance curing compound currently available on the Australian market.
Evencure X-Pose Concrete Surface Retarder is a uniquely formulated liquid that retards the surface of the concrete, whilst allowing the subsurface to still harden.
WHAT IS CURING?
Curing has a strong influence on properties of hardened concrete such as durability, strength, watertightness, wear resistance, volume stability and resistance to freezing and thawing.
When Portland cement is mixed with water, a chemical reaction called hydration takes place.
The extent to which this reaction is completed determines the strength, durability and density of the concrete. Most fresh concrete contains considerably more than enough water for completed hydration of the cement; however any appreciable loss of water by evaporation or otherwise will delay or prevent completed hydration. Since hydration is relatively rapid the first few days after fresh concrete is placed, it is important for the water to be retained during this period, that is, for evaporation to be prevented or at least reduced.
WHY CURE CONCRETE?
The objects of curing are:
• To prevent the loss of moisture
• To control the concrete temperature for a definite time
With proper curing, the concrete will become stronger and more resistant to stress, abrasion and frost. The improvement is rapid at early ages but continues more slowly for an indefinite period. When moist curing is interrupted, the development of strength continues for a short period and then topes. However, as moist curing is resumed, strength development will be reactivated. Loss of water will also cause the concrete to shrink, thus creating tensile stresses at the drying surface. If these stresses develop before the concrete has attained adequate tensile strength, surface cracking can result. Exposed surfaces, including exposed edges and joints, must be protected against moisture evaporation.
